Hands-On Network Programming with C

By: Lewis Van Winkle

Overview of this book

Network programming enables processes to communicate with each other over a computer network, but it is a complex task that requires programming with multiple libraries and protocols. With its support for third-party libraries and structured documentation, C is an ideal language to write network programs. Complete with step-by-step explanations of essential concepts and practical examples, this C network programming book begins with the fundamentals of Internet Protocol, TCP, and UDP. You’ll explore client-server and peer-to-peer models for information sharing and connectivity with remote computers. The book will also cover HTTP and HTTPS for communicating between your browser and website, and delve into hostname resolution with DNS, which is crucial to the functioning of the modern web. As you advance, you’ll gain insights into asynchronous socket programming and streams, and explore debugging and error handling. Finally, you’ll study network monitoring and implement security best practices. By the end of this book, you’ll have experience of working with client-server applications and be able to implement new network programs in C. The code in this book is compatible with the older C99 version as well as the latest C18 and C++17 standards. You’ll work with robust, reliable, and secure code that is portable across operating systems, including Winsock sockets for Windows and POSIX sockets for Linux and macOS.

What is the IoT?

We now live in a world where almost anything that can be connected to the internet, has been. These devices make up the IoT, and they are in every part of our lives.

In the kitchen at home, devices with internet connectivity include fridges, microwave ovens, conventional ovens, food scales, dishwashers, coffee-makers, and even juicers.

Elsewhere in the home, we have smart TVs, gaming consoles, thermostats, furnaces, washing machines, light switches, light bulbs, yoga mats, alarm clocks, cameras, doorbells, bathroom scales, baby monitors, sound systems, and speakers—all connected to the internet. Of course, your whole house may be supplied with electricity, water, and gas from networked smart meters. When you leave home, do you go through an IoT garage door to get in your always-connected car with built-in Wi-Fi? Many do.

In the industrial sector, IoT devices are central to Industry 4.0, commonly considered the fourth industrial revolution. Using internet connectivity to interconnect...
